If you add it ten times over you're trying to add the same button to the container not ten different buttons. Using new Button() gives you a new button, so writing b1 = new Button(); this.addChild(b1); creates a new Button, points b1 at it and adds it to the display list. Do it again and then b1 points to a different Button.. The mxml tag notation not only refers to the Button class but also instantiates a seprate instance, so you would get ten different buttons.
